Not correct length
Would Not RecommendI bought 4 rolls. All 4 were less than 100’ long. All came out between 95’ and 98’. The product does work but being shorted sucks

Easy to use, but...
Would RecommendI have ordered this item twice. Good product, easy to use, but..the first roll was 10 inches short of 100 feet, and the second roll was 8 inches short of 100 feet. So I had a gap after installation of my last sheet.
